lCrE 'I i COIL WINDER.

pplication led February 28, 1925. Serial Nic. 12,202.v v 'y elongated narrow coil, and afterwards shape that coil to the desired form by pulling Tit apart and bending its different portions ac'- particular pattern of they cording to the rotor, stator, or other part to which the coil is to be applied. Excepting in the very smallest of machines the wire used in these coilsis generally of considerable size and stiffness and is wound under very considerable tension so that difficulty has heretofore the winding" of its parts,

. j ing apart of this application I have shown been experienced 'in removing the coil from form without di'sarra-ngement injury to the insulation, or undue delay in the manipulation. y

i The objectsofthepresent invention are the provision of a winding form havingnew and improved arrangements for holdingthe coil'during the .winding and releasing the same when wound; the provision of a device of thisv nature whereinthe abutments upon which the coilis wound can v`be quickly and conveniently retracted so as to free the coil and afterwards restored into extended position for 'the reception of a succeeding coil; the provision of new and improved `expedients for fasteningv and releasing the removable part whichl shapes the `outer face ofthe coil;vv while further objects and advantages of the invention'will become apparent as' the description proceeds.

In the drawings accompanying and formkone physical embodiment of my inventive idea although it will be understood that these 'drawings are intended to be ymerely illustrative of the general principles of. my invention and not exhaustive as to detailed constructions. Y

Fig. 4 is a sectional view Correspending to the lille 4,-4 of Fig. 3 looking upwardly;- Fig. 5 is a sectional viewy corresponding to' the brolrenline 5-'-5`in Fig. 4; Fig. 6 is a yseparated perspective viewr of `one` of the abutments'and cheek pieces and sectional view u Fis 7, is 21 lcorresponding to the line 7-7 j Forpurposes of illustration I have shown a mechanicallyV operated` Winder comprising a stand orV support 1 having journaled'therey V in a horizontal shaft 2' provided with a face .plate 3 to which is tightly secured the base member of my improved winder.' This member is formed at opposite sides with radial arms 5-.1-5 having outwardly extending spacing projections 6-6 at their ends. 'rightly-secured to these projections is a rectangular bar 7 extending diametrically past the'end-ofy the shaft and having' i slidably mounted tliereona pair of hollow l blocks or carriers 8-l-8.` These carriers are mounted and secured in place in any suitable manner, inthe present yinstance by'enibracing the bar 7 and-being provided at their bottomsl with removable plates 9 in eachl of which is mounted a pivoted `turret 10 traversedv byl a'longlthreadedrod 11.

` At the middle of the bar 7 I mount a rock shaft 15 lhaving at one end the handle 16 and at the other endv the block 17 4'lPivoted to this block upon opposite sides of the rock shaft are eye-bolts 18-18 in which are swiveled the inner endsiof the rods'11-'11. When the block 17 vis turned to a position parallel with the bar `7 the carriers 8-8 occupy theirpositions lof greatest separation but by rotating the rock shaft 15 as shownby the dotted' lines inFig.` 7 the rods11 are causedy to retract'xsaid carriers by equalv amounts.l The outer ends Vof the rods 11 y are formed with prisinatic portionsl 19'-`19 for the reception of a ysocket wrench which can be inserted through holes 20w-20 in the projections -6-6 thus enabling 'an' adjustment of the distance between the carriers and hence the'length of the coil. V f l Projecting outwardly from the Outer faces of the carriers 8-8 arethe abutment menibers 244-24 onffwhich the coil is wound. In

their preferred vform these abutment inembers kconsist' of elongatedslianks 25 adjustably secured in 'slots' 2G and-secured by boltsv 27. vThe edges yof 'these .sided portions 30-30 the center of the bar.

tion of the wire and their outer ends are formed with suitable heads for the reception of the removable cheek pieces. In the form' herein shown these heads'consist of squareprojecting away trom ing a rod 34 secured to one member and a tube 35 connected to the other member, a suitable clamping device 86 being provided whereby the parts can be secured together. In the present embodiment I have shown .the cheek pieces 82 as semi-circular, subtending only the outer portion of the turn ot the coil,

while the cheeks 3l are completely circular, being intersected only'by the slots These are vminor details and are mentioned only to facilitate an understanding` of the embodiment shown .in the presentdrawing.

In use the cheek-pieces 32'are applied to the heads as illustrated in Fig.. il, the abutments being so adjusted in their slots as to space the same from the cheeks 31 a sailicienty distance yto accommodate the coil 40, the clamp 36 being tightened atA such a point as shall hold `the members tightly when the abutments, are expanded. One end of theV wire is secured to a suitable clamp 41 carried ony a suitable point on the vrotating arm and the head slowly revolved, the Wire being guided into the slots under substantial tension thereby forming a long narrow coil 40 asshown in Figs. 2 and 4. When the winding iscomplete and before the coilis removed it may betiedtogether by suitable wires ll-lxso as to hold the turns in position. The termina-ls 42 of the kwire are also genorally brought'out parallel `to each other as shown in Fig. y2, one of the same often being bentat this time from someother position suchas that shown in dotted lines aty 43. The handle y16 is then rocked as hereto-fore describedso as to retract the abutments as shown Figs. l and 2 whereupon the re movable .cheek `pieces are instantly released to the detailed shape and all ytension removed from the coil so that the same can be readily removed and f laid 4to one side after which the removable cheek pieces are replaced, the handle restored to its former position, and the operationfrepeated.

It will be understood that I do not limit myself to the particular form of slide bar 7 herein shown or to the particular mode of 4 expanding and retracting the abutments, nor of the cheek-pieces,
